TA-repeat microsatellites are closely associated with ARS consensus sequences in yeast chromosome III

Abstract

Microsatellites are repeats of very short sequences of DNA, interspersed in the genome. In this paper, the occurrence of the two-base repeat microsatellites has been investigated in the DNA sequence of yeast chromosome III. Only AT-repeats were found at a significantly high frequency. Some of the regions with the highest concentration of AT-repeats were located and further analysed, showing a close association with the core consensus of autonomously replicating sequences.
